Product Overview
The HW450DS is a high-power dual-handle model in the Denvo/engine welder Diesel Engine-Driven Welders series. It is equipped with an international brand diesel engine and digital IGBT control technology. It is rated Welding Current 50-450A. A single device can drive two welding guns independently at the same time. The equipment has its own power generation power supply, no external power grid is required, and with 6kVA/15kVA (220V/380V) auxiliary power output, welding and on-site power consumption can be realized at the same time, which is an ideal choice for two-person continuous operation scenarios such as municipal pipe network, pipe prefabrication, and building steel structure.
Different from the traditional single-handle welding machine, the HW450DS uses a dual-station independent output architecture, allowing two welders to set their respective welding currents on the same equipment without interfering with each other, effectively improving the output capacity of the construction team’s single equipment and reducing the number of equipment inputs and transition costs.
Double Handle Dual-arc welding Technology Explained in Detail
The core of the HW450DS is the dual-handle double-arc welding technology: one engine drives two sets of independent welding circuits at the same time, each set of circuits has independent current regulation and control, two welders can choose the current gear suitable for their own welding electrode specifications, without affecting each other.
- Improved efficiency: Single equipment supports two people to weld at the same time, which significantly improves the construction schedule and shortens the project period compared to single person and single operation.
- Independent control: Dual stations independently set the current to adapt to different electrode diameters and welding positions, and flexibly respond to a variety of construction scales.
- Stable on output.: Digital IGBT control achieves precise arc adjustment, smooth arcing, beautiful weld formation, and rework rate is reduced.
- to be undergoing works: 100% continuous load rate design, with large capacity fuel tank, to meet the needs of long-term continuous construction work.
